Library commands:

• TeTRiS2 Strarts new game using actual settings.
• Top5 Shows high scores for each mode.
• Modo Shows a menu to change the mode with which a new game is started. In basic mode there are no weird tiles, while in other modes they will show up.
• Lineas Shows a menu to change the initial rows with which a new game is started.
• Teclas Shows a menu to change the keys used during the game. By default scroll keys are used, and "P" to pause.

Note: While the game is paused (notice the small flag next to the score) the calculator can be tuned off by pressing the OFF key, or the game can be saved by pressing the STO key. Any other key will resume the game. After saving the game an object is left on stack level 1, to continue evaluate this object.
